Thatcher wasn't human - or certainly didn't show any humanity, so she doesn't count.
Don't rule Gove out. He's weasely enough and connected enough with the media to cheat his way to the top job....
I don't want him to win like, I'd far rather see him do a job he's actually qualified for. Perhaps changing toilet rolls in public lavvies - I don't think there's much he could do wrong there. But if he did, he could knacker the Tories.
